Dogs most definitely communicate. They communicate with body language and with verbal language. I can have a dog outside, too far across the yard to know that I'm getting their dinners ready. One dog in the house barks and the dog outside comes running and makes a beeline for his cage so he can eat. Other barking wouldn't have that effect. It indicates to me that there is something in the inflection of the barks that absolutely functions as a language.
Dogs communicate with verbal language? Really? Verbal language refers specifically to the use of words. What words has your dog used? Isn't it just possible that what you interpret as "inflections" in the barks (which somehow count the same as words in your mind) are just unconscious expressions of different emotional states? If you step on a dog's paw is his vocalization (note this word here -- vocalization,not verbalization) somehow NOT going to be an expression of his emotional state? If he's angry or aggressive is his barking NOT going to reflect his emotional state? So how does the dog who's inside the house, and knows that dinner is on the way somehow become capable of intentionally using a certain inflection in his voice to report information to his cohort that it's time to eat, and not just express his unconscious emotional state of excitement that dinner is one the way, and nothing more?
I don't mean to beat up on you, CorgiP, and it's kind of pointless for me to keep explaining this, but here goes:
There are two types of communication:
The first is the intentional reporting of information with the expectation that whomever you're communicating with is capable of understanding what you're saying. This absolutely requires the use of symbols, written, spoken, or signed (as in sign language). Inflection provides information about one's internal state, but it doesn't count as language, in and of itself. This first type of communication also requires that whoever is reporting information has to have what's called a theory of mind*.
The second type of communication is the expression of an internal state, which even in humans is most mostly done unconsciously. This can be done with the use of symbols (written, spoken, or signed), or with unconscious use of body language, facial expressions, sighs, tears, laughter, what have you. It's not the same thing as reporting information. When the second dog in your example responds as he does, it's not because the first dog deliberately and with conscious intent reported information to him. You can't report information without the use of symbols. (Expressions of emotion aren't symbols.)
And going back to one of Ron2's questions in another post, the simple biological fact is dogs do not have the cognitive architecture for language (Broca's area, Wernicke's area, etc.) They don't have a hyoid bone in their throats so they cannot possibly express themselves verbally. They DO express their emotions, and quite freely, and quite often, and quite wonderfully, But not as a way of intentionally reporting information (which, once again, would require the use of symbols, written, spoken, or signed, and what's called a theory of mind). So when one dog barks in an excited way at dinner time he's not reporting information to the other dog; he's only barking, which is an expression of arousal. The other dog recognizes the emotion in the first dog's voice, which sparks an emotion in him. So he comes running.
Feel free to entertain yourselves with fantasies about a dog's linguistic abilities all you want. I've been studying this topic for over 15 years. And I've been "donating" my time* on sites like this to explain why this silly belief in a dog's ability to use language is such a fantasy. I've probably discussed this issue with thousands of dog owners and dog trainers. And not one of them, including you, has yet come up with a situation that can't be explained purely through emotion, and which does NOT require conscious thought, ToM, or the use of symbolic language.
But feel free to entertain yourself with your fantasies if you like.

*Theory of mind is the ability to attribute mental states—beliefs,
intents, desires, pretending, knowledge, etc.—to oneself and others. It enables one to understand that mental states can
be the cause of—and thus be used to explain and predict—others’ behavior. Being able to attribute mental states to others and understanding them
as causes of behavior means, in part, that one must be able to conceive
of one's own mind as a means of representing reality, through an ability to be aware of one's own sensory input as a representation of the natural world (in other words to not only see and hear things, but to also know that you're seeing and hearing them), as well as an ability to form abstractions, concepts, and symbols which represent reality. That's just the first step. The second is to understand that other beings have minds and that the mental representations of the world being made in their minds do
not necessarily reflect reality and can be different from one’s own. It
also means one must be able to maintain, simultaneously, different
representations of the world. It is a ‘theory’ of mind in that such
representations are not "directly observable". Many other human abilities—from skillful social interaction to language use—are said to involve a theory of mind.
If you can explain to me how a dog can even have first level cognition, an awareness of his own mental states, that would, once again, only be a first step to having a theory of mind. He would also have to be able to be aware that people and other dogs have mental states of their own, which are both similar and capable of being dissimilar to one's own mental states. Prove dogs have that ability and we can all go home...
**Why? Because the more dog owners believe in this fantasy that dogs can think and use language, the more likely it is that when the dog does something "bad," the owner will think it's been done deliberately, and will punish the dog to let him know he can't get away with it, etc. If people have the realistic, down-to-earth view I'm expressing, the less likely it becomes for such owners to mistreat their dogs.
